Ultrasonic Mouse Repeller, Indoor Electronic Pest Repellent Plug in Powerful Pest Control for Mouse, Mice, Spider, Cockroaches, Ants, Fly, Rodent, Harmless to Pets and Human, Eco-Friendly (4Pack)

I appreciate the compact design of these devices, which allows them to remain inconspicuous while effectively repelling mice. The straightforward setup involves a simple plug-in, and the ultrasonic sound emission begins promptly. Surprisingly, the traditional traps failed to yield results, but these devices exceeded my expectations! After plugging them in, I observed no signs of mice the following day. I’m thoroughly satisfied and highly recommend them

We had some unexpected visitors in our house that were causing me a lot of distress. I had to clean and disinfect all the time everywhere as I have a baby. The usual traps didn't work so I thought to give these devices a try but I didn't expect them to work. I plug them all in throughout the house and the next day I checked the house and couldn't find any evidence of the mice being there. I wanted to give them more time to see if they really worked. More than 2 weeks later and still no sign of the mice. Couldn't be happier. What I can say is that they really work and worth buying.

how does this work? are your reviews honest and genuine? cant see how they are remotely effective. seems like a waste of money. no information about the product came with it on delivery niether.

Seems to work well. Difficult to get used to the clicking sound, but appears to be working since purchased 2 weeks ago

I love the fact these devices are small, compact and can be placed out of sight and still work. They are simple and easy to setup, simply plug in and it'll start producing ultrasonic sound that repels creepy crawlies.A little on the fence as to it's effectiveness but pleasantly surprised so far. The rooms I've used them in are large so I've put two in each room and I do think they work. Price is very reasonable and seems a decent price for a pack of four.

I recently purchased a pack of four plug-in ultrasonic Tomus pest repellents to address a persistent scratching noise in our apartment walls, indicating the presence of a larger rodent than a mere mouse. Desperate for a solution, I decided to give these ultrasonic repellents a try, and I couldn't be more satisfied with the results. Within just a few days of installation, the scratching noises that had been driving us crazy stopped entirely! These repellents are incredibly easy to use – just plug them into any available wall socket and they start working silently. Their comprehensive coverage ensures every corner is protected. I highly recommend these repellents for anyone dealing with pest issues!

Really good product. It works as advertised. After a few days, I saw drastically reduced pest activity and I could not even hear it working. I got five and will use all the rest throughout the house because of how much I like it. I couldn't recommend these enough.

My mice walk right past these… don’t waste your money. Have no idea how these have so many 5 star reviews.
